Vomit is a great way to stay home or get revenge. Instead of making yourself sick on purpose, why not make some fake vomit instead? There are lots of ways to make it using stuff from your kitchen. Vomit is just mixed up food from your last meal, so you can use just about anything. There are some recipes you can use to make it extra-gross and realistic, however. You can even use glue to make it reusable!

Chew up some crackers. You can also break them up with your hands as well.[1]XResearch source If you can't find any crackers, you can use biscuits or light-colored cookies (ie: vanilla wafers, sugar cookies, graham crackers, etc.). Don't use chocolate chip cookies or Oreos—those are way too dark!

Add some water, if needed. If you spat the crackers into a toilet, you don't need anymore water. If you spat them into a bowl, bag, or sink, then add in a little water. This makes the vomit look more real.[3]XResearch source

You can also try some white vinegar, apple cider vinegar, apple juice, or even a little milk.

Add something mushy and smelly. Wet cat food or wet dog food work great for this. You can also use a little bit of canned tuna or baby food. It will help make the vomit look (and smell!) more real.[4]XResearch source You could also chew up some cereal, spit it out, then mix it with vinegar.

Add some on the toilet seat. It'll look like you missed![5]XResearch source

Let the vomit cool before you use it. Pour it down the front of your shirt, or dump it into the toilet. Get some on the floor. You can also take some into your mouth, then lean over and spit it out. Make some puking sounds![12]XResearch source

Heat up ¼ cup (45 grams) of applesauce. Pour the applesauce into a small pan, and place it on the stove. Turn the heat up to low or medium. Wait for the applesauce to get hot enough to make steam.[13]XResearch source

Any type of applesauce will work. If you can't find any, try baby food.

Add in 1 to 2 pinches of cocoa powder. Give the vomit another stir. Sprinkle it over the contents in the frying pan and stir. This will help give the vomit some color.[15]XResearch source If you can't find any cocoa powder, you can use hot chocolate mix or even a pinch of dirt.

Add in some oatmeal and cereal for texture. You will need a small handful of each. Give the vomit another stir to mix everything in.[16]XResearch source If the cereal has large flakes, you can crumble them with your hands first.

If you don't have Raisin Bran or Cornflakes, you can use another type of brownish, flaky cereal. Granola is a great one!

Spread the fake vomit onto a plate. Use a spatula to move the vomit from the pan to a plate. Spread it around into a vomit shape with a spoon. If you want to, you can add more oatmeal or crushed cereal on top.[17]XResearch source Don't get too carried away!

Pour half of it out onto a sheet of parchment paper. Place the parchment paper onto a baking sheet first. Next, pour the glue onto the parchment paper into a vomit shape. Save the rest of the glue for later.[22]XResearch source

Add something chunky. A handful of dry cat or dog food will look gross. If this is human vomit, you could try a handful of dry oatmeal or granola. Put most of the chunks in the middle of the glue puddle, and a few bits on the edges.[23]XResearch source

Cover the chunky bits with the rest of the glue. Simply pour the rest of your colored glue over the vomit puddle. Make sure that you cover all the chunky bits you added in. This will help seal them in.[24]XResearch source

Wait for the glue to dry. The glue will turn clearish once it dries. This may take a few days. If you get impatient, let it dry for about 48 hours, then bake it for about 10 minutes in the oven at 275°F (135°C).[25]XResearch source

If you want to bake it, open up a window. It will stink!

Don't put wax paper or plastic wrap into the oven. If you used those, you'll have to let it air dry.

Peel the vomit off. The glue will dry semi-flexible, but be careful not to bend it too much. Leave the vomit some place for your victim to find, like the floor or their pillow. Because this vomit is made from glue, it should last a very long time.[26]XResearch source

Milk and chewed up chunks of bread work, too. Vomit is pretty much just mixed up food. You can also put random food items into a blender, along with some water, milk, juice, or vinegar, and use that instead.

I didn't have any of the ingredients either and I made it work. Just chew up a handful of raisins and put them in the toilet or a bowl and add water (stir to make sure color keeps consistency throughout). I did not think this would work since my mom is a doctor, but one look at the toilet bowl (I splattered the mix across for extra measure) and I was staying home for that whole day!

You can place the concoction in a plastic bag and heat with a hair dryer (not recommended, as it's very loud) or a heating pad. You could also let it sit over a vent in the winter or on your windowsill in the sun in the summer.

Mix it with some milk and let it sit past it's expiration, it’ll give it a nasty smell. If that’s not helpful, try and take whatever food you ate earlier that day, they should know what you ate that day so they will notice the little food chunks of the food you ate that day.

To make fake vomit with glue, start by squeezing about ¼ to ½ cup of glue into a plastic cup. Then, add 1 drop of brown food coloring or paint to the glue and stir it well with a spoon or toothpick. Next, pour half of the glue onto a parchment paper-lined baking sheet and add some sort of chunky food pieces, like dry cat food or granola. Cover the chunky parts with the rest of your glue to seal them in, and wait about 48 hours for everything to dry. Once it’s dry, place the baking sheet in the oven and bake the glue at 275°F for 10 minutes before peeling off. To learn how to make fake vomit with crackers and water, read on!
